RYOBI TECHNOLOGIES, INC. LIMITED WARRANTY FEDERAL AND CALIFORNIA 

EMISSION CONTROL SYSTEMS NON-ROAD AND SMALL OFF-ROAD ENGINES

The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and Ryobi Technologies, Inc. are 

pleased to explain the Emission Control System Warranty on your non-road or small off-road engine. In California, new small 

off-road engines must be designed, built and equipped to meet the state’s stringent anti-smog standards. In other states, new 

2000 and later model year non-road engines must be designed, built, and equipped, at the time of sale, to meet the U.S. EPA 

regulations for small non-road engines. The non-road engine must be free from defects in materials and workmanship which 

cause it to fail to conform with U.S. EPA standards for the first two years of engine use from the date of sale to the ultimate 

purchaser. Ryobi Technologies, Inc. must warrant the emission control system on your non-road or small off-road engine for 

the period of time listed above provided there has been no abuse, neglect, or improper maintenance of your non-road or small 

off-road engine.
Your emission control system may include parts such as the carburetor or fuel injection system, the ignition system, and the 

catalytic converter. Also included may be hoses, belts and connectors, and other emission related assemblies.
Where a warrantable condition exists, Ryobi Technologies, Inc. will repair your non-road or small off-road engine at no cost to 

you, including diagnosis (if the diagnostic work is performed at an authorized dealer), parts, and labor.

MANUFACTURER’S WARRANTY COVERAGE:

The 1995 and later small off-road engines are warranted for two years in California. In other states, 1997 and later model year 

non-road engines are also warranted for two years. If any emission-related part on your engine is defective, the part will be 

repaired or replaced by Ryobi Technologies, Inc. free of charge.

OWNER’S WARRANTY RESPONSIBILITIES

(a)  As the non-road or small off-road engine owner, you are responsible for the performance of required maintenance listed in your 

operator’s manual. Ryobi Technologies, Inc. recommends that you retain all receipts covering maintenance on your non-road or 

small off-road engine, but Ryobi Technologies, Inc., cannot deny warranty solely for the lack of receipts or for your failure to ensure 

the performance of all scheduled maintenance. Any replacement part or service that is equivalent in performance and durability 

may be used in non-warranty maintenance or repairs, and shall not reduce the warranty obligations of the engine manufacturer.

(b) As the non-road or small off-road engine owner, you should be aware, however, that Ryobi Technologies, Inc., may deny you 

warranty coverage if your non-road or small off-road engine or a part has failed due to abuse, neglect, improper mainte-

nance, or unapproved modifications.

(c)  You are responsible for presenting your non-road or small off-road engine to a Ryobi Technologies, Inc., service dealer as 

soon as a problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 

days.

If you have any questions regarding your warranty rights and responsibilities, you should contact a Ryobi Technologies, Inc., 

Customer Representative at 1-800-860-4050.

COVERAGE:

Ryobi Technologies, Inc. warrants to the ultimate purchaser and each subsequent purchaser that your non-road or small off-road 

engine will be designed, built, and equipped, at the time of sale, to meet all applicable regulations. Ryobi Technologies, Inc. also 

warrants to the initial purchaser and each subsequent purchaser that your non-road or small off-road engine is free from defects in 

materials and workmanship which cause the engine to fail to conform with applicable regulations for a period of two years. The 1995 

and later small off road engines are warranted for two years in California. In all other states for 1997 and later model years, EPA requires 

manufacturers to warrant non-road engines for two years. These warranty periods will begin on the date the non-road or small 

off-road engine is purchased by the initial purchaser. If any emission-related part on your engine is defective, the part will be 

replaced by Ryobi Technologies, Inc. at no cost to the owner.
Ryobi Technologies, Inc. shall remedy warranty defects at any authorized Ryobi Technologies, Inc. engine dealer or warranty sta-

tion. Any authorized work done at an authorized dealer or warranty station shall be free of charge to the owner if such work deter-

mines that a warranted part is defective. Any manufacturer-approved or equivalent replacement part may be used for any warranty 

maintenance or repairs on emission-related parts, and must be provided free of charge to the owner if the part is still under warranty.  

Ryobi Technologies, Inc. is liable for damages to other engine components caused by the failure of a warranted part still under warranty.
The California Air Resources Board’s Emission Warranty Parts List specifically defines the emission-related warranted parts. 

(EPA’s regulations do not include a parts list, but EPA considers emission-related warranted parts to include all the parts listed 

below.)
These warranted parts are: Carburetor, Spark Plug, Ignition, Air Filter, and Fuel Filter.

MAINTENANCE REQUIREMENTS

The  owner  is  responsible  for  the  performance  of  the  required  maintenance  as  defined  by  Ryobi  Technologies,  Inc.  in  the 

operator’s manual.

LIMITATIONS

The Emission Control Systems Warranty shall not cover any of the following:
(a)    repair or replacement required because of misuse or neglect, lack of required maintenance, repairs improperly performed 

or replacements not conforming to Ryobi Technologies, Inc. specifications that adversely affect performance and/or du-

rability, and alterations or modifications not recommended or approved in writing by Ryobi Technologies, Inc., and

(b)   replacement of parts and other services and adjustments necessary for required maintenance at and after the first sched-

uled replacement point.

hours.
